What generation SGI hardware? All but some *very* recent SGI/IRIX
systems require 512byte block mode support, and older systems
(including many early Indigo2s) *must* have the drive hard configured
by jumper (or hard set in firmware) for 512byte blocks. Later I2s and
whatnot will automagicly set a drive to 512 byte block model at boot
via SCSI command (Any SCSI PleXtor, most SCSI Sony, any SCSI toshiba
with *Nix firmware).

Most Sun hardware (including many UltraAXi and AXMP platforms)
requires it to be set by jumper (some openboot proms will set via SCSI

I route, therefore you are.
